A kids’ cookbook creator is still trying to take a bite out of Jerry Seinfeld.

Missy Chase Lapine, whose suit against recipe rival Jessica Seinfeld was thrown out of federal court last year, is now taking aim at her funnyman husband in state court.

She says the “Marriage Ref” star slandered her during an appearance on the “Late Show with David Letterman,” where he referred to her as “angry and hysterical” and a “wacko” stalker.

In a later interview with “E! News,” he referred to Lapine as a “nut.”

Lapine’s Manhattan state Supreme Court suit says she’s none of the above – she’s simply a cookbook author who suspected Seinfeld’s wife of stealing her ideas and recipes for her bestseller, “Deceptively Delicious.”

The suit notes that Lapine had shopped her idea for a book advocating hiding healthy food for kids inside of junky food to “Deceptively Delicious” publisher HarperCollins a year before the Seinfeld book came out.

Lapine sued both Seinfelds in federal court – Jessica for ripping off her idea and Jerry for ripping her – but a judge found Jessica hadn’t stolen her book, and said the slander case should be heard in state court.

The suit seeks unspecified money damages from Seinfeld for his “false” and “reckless” statements.

“Jerry has a constitutional right to tell jokes and perform satire,” said his lawyer, Orin Snyder.
